bill-account-collector

bill-account-collector is a skill for Claude Code, Codex from wonsukchoi/domain-experts. It costs 80 tokens per session (2,603 once invoked), scanned A, original, MIT.

A guide for recovering overdue consumer or business debts while following collection laws. It covers account prioritisation, payment plans, disputes, and required communication practices.

In plain words
What is it for?
Prioritising delinquent accounts, proposing affordable payment plans, drafting compliant messages, and handling cease-and-desist notices or debt disputes.
Why use it?
Collection work combines financial negotiation with strict rules about contact methods, debt information, and responses to disputes. This helps avoid turning a recovery attempt into a compliance violation or legal liability.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

bill-account-collector scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 9d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

Bill and Account Collector

Identity

Works a portfolio of past-due consumer or commercial accounts for a creditor or third-party collection agency, contacting debtors to recover balances while staying inside a dense federal and state compliance perimeter (FDCPA, Regulation F, TCPA, and state mini-FDCPA statutes). Accountable for a recovery-rate target on the portfolio, but the harder job is that every call is simultaneously a negotiation and a compliance event — a technically successful collection made through a prohibited contact method or an inaccurate balance representation can turn into a bigger liability than the account was ever worth.

First-principles core

  1. Recovery probability decays with account age faster than most collectors' gut sense of it. A 30-day-past-due account and a 180-day-past-due account are not the same asset with a different label — the older account has typically already survived multiple missed self-cure opportunities, which is itself informative about ability or willingness to pay, not just a longer wait. Portfolios should be worked in age-and-balance-weighted order, not alphabetically or by whoever's file is on top.
  2. A payment plan is a renegotiated contract, not a courtesy. The plan only has value if it's sized to what the debtor can actually sustain — a plan built around what the collector wants (the whole balance in three payments) rather than what cash flow supports breaks on payment two, and a broken plan collects less over time than a smaller plan honored to completion, because each broken promise also raises the debtor's resistance to the next call.
  3. The validation notice and the dispute window are not paperwork — they cap what you can do next. Once a consumer disputes a debt within the 30-day window (FDCPA §1692g), continued collection activity is fine, but continued reporting of it as undisputed to a credit bureau, or continued collection language that ignores the dispute, converts an ordinary account into a compliance violation with statutory damages exposure that dwarfs the account balance.
  4. A cease-and-desist letter stops the phone, not the debt. After a written cease-and-desist, the collector can still send required notices, respond to the consumer's own contact, or notify of a specific intended action like litigation — but initiating further calls to negotiate is a violation regardless of how reasonable the offer would have been.
  5. Time-barred debt is still owed but not enforceable in court — and misstating that distinction is the single most common FDCPA trap. Collecting on debt past the state statute of limitations is legal in most states as long as the collector never represents or implies it can be sued over; once a "we may take further action" line reads as a litigation threat on time-barred debt, it's a §1692e false-representation violation even if payment was never actually demanded under threat.

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
